What is a good ROAS?

There is no universal "good" ROAS. The only number that really matters is your break-even ROAS — the return at which ad-driven revenue covers both your ad spend and the cost of what you sold. A good ROAS is simply one that sits comfortably above it.

That's why the same figure means opposite things for different businesses: a 4× ROAS is excellent for a high-margin software product and a loss-maker for a thin-margin retailer. The useful question isn't "what's a good ROAS?" — it's "what's a good ROAS for my margins?"

Is a 4:1 ROAS good?

You'll often see 4:1 (a 4× return, or 400%) quoted as a good ROAS. It's a fair rough anchor for a mid-margin ecommerce business — but it's a starting point, not a rule. A high-margin business (software, digital products) can be very profitable at 2:1, while a low-margin one (dropshipping, thin retail) can lose money at 4:1. Treat 4:1 as "somewhere in the normal range," then check it against your own break-even.

Break-even ROAS — the real answer

Your break-even ROAS is the point where the profit from ad-driven sales (revenue minus the cost of what you sold) exactly equals your ad spend:

Break-even ROAS = 1 ÷ profit margin

A 50% margin needs a 2× ROAS just to break even; a 25% margin needs 4×; a 20% margin needs 5×. Below your break-even you lose money even though the ROAS looks "positive" — above it, the gap is your profit. This is exactly why a single "good ROAS" figure is meaningless without knowing your margin.

The break-even ROAS calculator turns your margin into the exact ROAS you need to beat, the ROAS calculator works out your actual return, and the Campaign Forecast models break-even and profit across conservative, realistic and optimistic scenarios.

How to judge your own ROAS

Compare it against three things, in order:

1. Your break-even ROAS — are you comfortably above it?
2. Your own history — better or worse than past campaigns?
3. Blended vs per-channel — a healthy blended ROAS (MER — your total revenue divided by total ad spend) can hide a single channel quietly losing money.

And never read ROAS alone: a great ROAS on tiny spend may not survive scaling, and ROAS ignores product costs entirely. Read it alongside your true profit and how much a customer is worth to you over time.

Prospecting vs retargeting ROAS

The same "good ROAS" figure means different things depending on where in the funnel a campaign sits. Retargeting (warm audiences who already know you) almost always posts a higher ROAS than prospecting (cold audiences you're introducing yourself to) — because you're harvesting demand you already created rather than building it from scratch. Judge a prospecting campaign against a retargeting benchmark and it looks like a failure when it may be doing exactly its job.

Two consequences: compare campaigns like-for-like by funnel stage, and don't starve prospecting just because its ROAS is lower — without it, retargeting eventually runs out of new people to convert.

Blended ROAS and MER

Platform-reported ROAS is measured per channel, and every platform tends to claim credit for the same sales — so the numbers can add up to more than 100% of reality. A more honest view is your blended ROAS, often called MER: total revenue ÷ total ad spend across everything. It's much harder to game and far closer to what actually lands in the bank.

The catch: a healthy blended number can hide a single channel quietly losing money — so watch both. Use the blended figure for the truth about profitability, and the per-channel figures to decide where to cut and where to scale.

Why your target ROAS shifts as you scale

The "good" ROAS you should aim for isn't fixed — it moves with your goal at each stage of growth. Three common postures:

• Growth / land-grab. To take market share fast, brands accept a ROAS close to break-even — sometimes below it on the first order — trading near-term profit for customers and volume.
• Profitability. To make money now, you pull budget back to your most efficient audiences, and the ROAS you require rises comfortably above break-even.
• Scaling. As you spend more, ROAS almost always falls — you exhaust your warmest audiences and start reaching colder ones. A lower ROAS at ten times the spend can still mean far more total profit than a high ROAS on a tiny budget.

This is the trap in chasing a single "good" number: maximising ROAS usually means shrinking, and a smaller, higher-ROAS account can make less money than a larger, lower-ROAS one. Set the target to the job you're doing — growth, profit or scale — not to a figure from a benchmark chart.

Frequently asked questions

Is a 4:1 ROAS good?

It's a common rule of thumb and fine for many mid-margin ecommerce businesses — but it's not universal. Work out your break-even ROAS (1 ÷ profit margin): if 4× sits comfortably above it, yes; if your margins are thin, a 4× ROAS may barely break even.

What's a good ROAS for ecommerce?

Many stores aim for roughly 3×–5× because of moderate margins, but the right number is set by your specific margin, not the sector. A high-margin or subscription brand can thrive lower; a thin-margin reseller needs more.

Can a high ROAS still lose money?

Yes. ROAS compares revenue to ad spend only — it ignores product, shipping and overhead costs. A 6× ROAS on a product with a 10% margin can still lose money once all costs are counted, which is why you read ROAS against break-even and true profit.

What's a good ROAS on Facebook or Google?

The platform matters less than your margins and funnel stage. Cold prospecting campaigns usually show a lower ROAS than warm retargeting ones — so compare like-for-like and against your break-even, not a platform average.

Key takeaways

• There's no universal good ROAS — it's set by your profit margin.
• Break-even ROAS = 1 ÷ margin; a "good" ROAS is comfortably above it.
• 4:1 is a rough anchor, not a rule — high margins thrive lower, thin margins need more.
• ROAS ignores product costs, so read it with break-even and true profit.
• Use the ROAS calculator + Campaign Forecast to model it.
